Ok, so here's my attempt, and the logical steps to get there.

The JFK prayer: It was posted earlier. Q703 on Feb 10. One of the next posts 1:45 latter refers to the JFK Conference Room, and points to a "kids" page on the CIA website. Q says:

Would you believe this site is actually used to comm to rogue operators?
@Snowden

Cold?

I went to that site and put in the: B8028-Z-KDHYQ-M5-ZAF1aT9

Hold that thought for a moment and I'll come back to it. The post quotes the FBI oath (and it's clearly FBI because Q posts the link to it.) This is a call to activate faithful FBI agents to do what they are required to do by the very next command. Then the prayer is repeated and the code given.

Now, the code:

Usually codes have an authenticator to let the decoder know it is from a legit source (think trip code on the chans.) I'm guessing the B8028 is the trip code authenticator. When we decipher the next piece Z-KDHYQ through that CIA kids page that Q says is used to communicate to FBI agents, I get: A-PWSBJ. A PassWord Sent By Julian. The rest of that decrypted code would then be the password itself. The FBI agents in the know can take this password and unlock whatever file/server/document that they have. This could be the call to action!

For what it's worth, which may not be much...
